The effects of temperature, time, and a catalyst on the distribution of the pyrolysis products were analyzed. The reaction temperature and time can significantly affect the types and yields of compounds produced by cellulose pyrolysis. A pyrolysis temperature of 500-600 °C and pyrolysis time of 20 s optimized the yield of volatile liquid in the pyrolysis products of cellulose. In all catalytic experiments, the relative contents of alcohols (1.97%), acids (2.32%), and esters (4.52%) were highest when K₂SO₄ was used as a catalyst. HZSM-5 promoted the production of carbohydrates (92.35%) and hydrocarbons (2.20%), while it inhibited the productioInternational journal of environmental research and public healthFast Pyrolysis of Cellulose and the Effect of a Catalyst on Product Distribution.PMC97797042021YFC2101604CJ 20220246Li YYang YSun TDong LLei TZhang LRen SfalseFast Pyrolysis of Cellulose and the Effect of a Catalyst on Product Distribution.Fast pyrolysis of microcrystalline cellulose (MC) was carried out by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS).
